Dual Forms of the Squares of Nijenhuis Tensor
Jun Ling
We express the dual forms of squares of Nijenhuis tensor in terms of the second order component derivatives of the exterior derivative on differential forms and give new vanishing…
The Square of Nijenhuis Tensor and Its Vanishing Results
Jun Ling
We give the strong form and the weak form of the square of Nijenhuis tensor, and some vanish results of the square.
A Class of Monotonic Quantities along the Ricci Flow
Jun Ling
We construct a class of monotonic quantities along the normalized Ricci flow on closed n-dimensional manifolds.
Some Asymptotic Behavior of the first Eigenvalue along the Ricci Flow
Jun Ling
We study some asymptotic behavior of the first nonzero eigenvalue of the Lalacian along the normalized Ricci flow and give a direct short proof for an asymptotic upper limit estima…
A Comparison Theorem and A Sharp Bound via the Ricci Flow
Jun Ling
We prove a comparison theorem for the compact surfaces with negative Euler characteristic via the Ricci flow.
The first Dirichlet Eigenvalue of a Compact Manifold and the Yang Conjecture
Jun Ling
We give a new estimate on the lower bound of the first Dirichlet eigenvalue of a compact Riemannian manifold with negative lower bound of Ricci curvature and provide a solution for…
